BUILDING CONSTRUCTION.

SPECIFIOATIQN forming part of Letters Patent No. 782,810, dated February 14, 1905. Application filed March 7,1902. Serial no. 97,133..

To all whom it may concern:

Be it known that we, JOHN H. MURPHY and ERVIN M. CAMP, citizens of the United States, and residents of the city of Chicago, in the county of Cook and State of Illinois, have in vented certain new and useful Improvements in Building Construction; and .we do hereby declare that the following is a full, clear,- and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form.

a part of this specification.

This invention relates to improvements in building construction.

The object of the invention is to provide a.

structure of concrete, cement, or other plastic material and metal so combined and associ-' atcd as to provide great strength with comparatively light weight and at a small expense, to economizing greatly in space and the cost of material, and to reduce the weight upon foun- In the drawings, Figure 1 is a perspective- .View showing the invention embodied in a partition or wall construction. Fig. 2 is a transverse'section of the same. Fig. 3 is a view illustrating one means for securing the reticulated structure to the corrugated sheet. Fig. 4 is a perspective view, partly broken, illustrating a column or'conduit' construction embodied in our invention. Fig. 5 is a sectional view of a construction similar tothat shown in Fig. 4, but showing the interior filled with concrete. Fig. 6 is a cross-section View illustrating a partition or wall construction.

As shown in said drawings, a sheet of metal A, which may be corrugated, as indicated in Figs. 1, 2, and 3, has permanently secured on one or both sides of the same in any desired manner a reticulated structure B, such as wirenet or expanded metal. The structure thus formed for whatsoever purpose used may then I be plastered with cement, mortar, concrete, or other desired material, thus not only greatly economizing in the amount of the plastic material used, but forming an exceedingly rigid structure having a perfect bond on the reticulated material and filling the corrugations'of the sheet and bonding therein; said sheet form? ing a tension member. This structure is especially adapted for wall and partition constructions,'and the sheet A when reinforced by the reticulated material B and the plastic I material forms a very rigid structure which is not only fireproof, but occupies a minimum,

amount of space.

In the construction of ceilings the sheet A,

having wire-netting or expanded metal-B se- I and is formed of wires twisted together in a' familiar manner. The sheet, with the net secured thereon, is then bentto a cylindric form gether by any desired means. thus formed is plaster-ed inside and out with cement of any desired material. When so plastered. the wire is firmly bonded in the cement and the meeting edges permanently secured to- I The cylinder and a very rigid and durable construction, is

provided. If preferred, indentations may be made in the sheet, as indicated at a", which provide projections alternately on opposite sides of the sheet and in which the mortar or other cement beds, aiding to rigidly hold the cement in position. Obviously pipes or tubular structures of any desired size and length may be constructed as described. I If preferred, said structure may be readily converted into an artificial-stone column by constructing the metallic shell as before described, which may be plastered on the exterior and the interior filled with concrete (J, as-indicated in Fig. 5, in

be made by bending the sheet A inwardly to provide a vertical recess to receive concrete, as shown in Fig. 6, .thus providing, in effect, the concrete studO', on opposite sides of which may be supported a wire mesh or other reticu lated material adapted to receive the plaster or cement. Clips a are provided on the sheet, either on the stud or on the sheets A, of which, if corrugated, the corrugations extend longitudinally and horizontally between the studs.

such as shown and which need not be corrugated, may be employed in constructing the stud. Within the same may be placed a sheathing of-reticulated material to form a; bond for the concrete, and concrete may be filled therein, forming a rigid column. Studs or columns of two inches or less in diameter may be thus I sirable or useful.

constructed, providing a thin partition.

The operationis as follows: Corrugated or other sheets when provided on oneor both sides thereof with areticulated. material which forms a rigid bond with the plaster or cement or concrete applied thereto provides a very rigid construction. If reticulated material such as wire-netting, expanded metal, or other suitable materialis placed on both sides, as indicated in Figs. 1. 2, and 3, a metallic and concrete board may be so constructed of little thickness and of great strength which may be adapted for almost any conceivable building purpose.

In use the metallic sheet forms a backing for the reticulated material and acts to greatly economize in the amount of the plaster or cement used and independent of the size of the mesh, or reticulations insures a perfect bond being made theron, affording amore positive support for the plasteror cement. Obviously the sheet instead of being corrugated may be indented at points to enable the plaster or-' cement to form abond or to clench therein,and, if preferred, the sheet may be a plain sheet, in which event the reticulated material being firmly secured and firmly clenched in the plaster, said sheet acting as a tension member in any position in which such a member is de- Obviously wheresuch plastered or cemented construction is exposed to the action of water, as in tunnel construcparticular uses herein shown and described.

Obviously many features of construction may be modified without departing from the principles of this invention.

We claim as our invention 1. A flexible metallic sheet having permanently secured thereon in close proximity therewith, approximately parallel with the surface thereof reticulated material having meshes therein too large to normally support the plaster and adapted when secured to said sheet to form a su pport for'plaster or othermaterial and to have the structureso formed entirely filled therewith and clips or tongues on said sheet adapted to permanently engage the reticulated material. a

2. The combination with a flexible sheet of sheet metal, of reticulated material secured on the sheet and an investing coating of adherent plastic material entirely filling and bonded on and in the'structure so formed.

3. The combination with a metallic sheet, of clips or tongues integral therewith,-reticulated material having meshes therein too large to normally support plaster and permanently secured on each side thereof by said clips or tongues in close relation and approximately parallel with said sheet, and plastic material such as plaster supported on both sides of the sheet filling the structure thus formed and affording an exterior finish.

4. The combination with an. unperforated 'sheet of flexible material, of indentations therein, of clips integral therewith, reticulated material lying flat against the sheet and permanently secured thereon by said clips.and plastic material rigidly engaged thereon by said indentations and reticulated material and entirely filling the structure.

.5. The combination with a metallic corrugated sheet havingclips alternately arranged on the apexes of its corrugations, of reticulated material rigidly secured on each side thereof, and a relatively thick layer of plastering material spread on the reticulations on each side of the sheet and filling the corrugations and reticulated structures.

6. The combination with a sheet of metal having a plurality of unperforated corrugations therein and interlocking clips thereon, ofsheets of reticulated material supported against the corrugations by said clips and ce- IIO . ing-clips thereon, reticulated structures permanently secured thereon and in close relation therewlth, a similar reticulation 0n the inner side of the casing, concrete or the like in said casing and engaging on the reticulated material and plaster on the outer side of the casing thus formed to afford a finish.

8. The combination with a sheet of metal having corrugations and bends therein, of a concrete filling in the spaces formed by the bends, reticulated material supported on the sheet in close contact therewith adapted to afford a support for a plastered finish.

9. A structure of the class described comprising a sheet of unperforated metal, corrugated and having alternate depressions in and projections on its surface, clips permanently subscribing witnesses.

secured on each side of the sheet, reticulated material having meshes therein too large to normally support plaster and permanentlylsecured on the sheet in close relation thereto and plastic material bonded in said reticulated material and entirely filling said structure.

10. In a device of the class described, the combination with a flexible, non-combustible sheet of clips or tongues thereon, reticulated metal secured on. said clips having meshes therein too large to normally support plaster and plastic material embedded in the structure thus formed and on the outside of the reticulated metal afiording a finish therefor.
